摘要
针对离网光伏通信基站供电系统,阐述了磷酸铁锂电池和铅酸蓄电池分别作为该供电系统的储能电池时的放电特性及应用情况。自建了一套离网光伏通信基站供电系统的演示应用系统并进行实测,分析了2种储能电池放电特性的差异,提出了光伏控制器差异化的充放电策略,为采用磷酸铁锂电池的离网光伏通信基站供电系统提供了系统控制策略的优化依据。
For the power supply system of off-grid PV for communication base station,the discharge characteristics and application of lithium iron phosphate battery and lead acid battery as the energy storage battery of the power supply system are described.A set of demonstration application system of the power supply system of off-grid PV for communication base station is built and by measured,the difference of discharge characteristics between the two types of energy storage batteries is analyzed,and the differentiated charge and discharge strategy of PV controller is proposed,which provides the optimization basis of system control strategy for the power supply system of off-grid PV for communication base station using lithium iron phosphate battery.
